E-07 Slow Decrease and Slow Increase of the Supply Voltage
The slow decrease and increase of the supply voltage is simulated as it occurs
during the slow decharging and charging procedure of the vehicle battery. The
waveform is as follows.
E-08 Slow Decrease and Quick Increase of the Supply Voltage
This test simulates the slow decrease of the battery voltage to 0 V and the sud-
den reconnection of the battery voltage e.g. by means of applying a jump start
source. The waveform is as follows.
E-09 Reset Behavior
The reset behavior of a component in its environment is simulated and tested.
Test boundary conditions (e.g. assembly, terminal, system) must be described
in detail.
During operation, an arbitrary sequence of repeated switching-on/off proce-
dures occurs; this must not lead to an undefined behavior of the component.
The reset behavior is represented by a voltage variance and a time variance.
Two different test sequences are required to simulate different switchoff times.
A component must always undergo both sequences.
